IonContent onScrollComplete undefined is not an object

Everytime I scroll a view it throw exception state below. I found this problem on IOS 8. No problem on browser with ionic serve.

Error:

TypeError: undefined is not an object (evaluating ‘scrollCtrl.scrollView.__scrollTop’)

Then I found out that the scrollCtrl is an empty object. Could it be the injector’s problem?

function onScrollComplete() {
  $scope.$onScrollComplete({
    scrollTop: scrollCtrl.scrollView.__scrollTop,
    scrollLeft: scrollCtrl.scrollView.__scrollLeft
  });
}

Hi peter, same is happening to me.
Have you by any chance figured out a solution?
